CNMG 090408 AH8015 — Tungaloy CNMG ISO turning insert for turning

A CNMG 090408 AH8015 indexable insert designed for general turning applications, offering a rhombic geometry and PVD-coated carbide grade for balanced wear resistance and edge stability in heat‑resistant alloys

• ISO-standard rhombic CNMG geometry
• PVD-coated AH8015 for heat‑resistant alloys
• Double-sided insert with cylindrical hole
• Corner radius 0.8 mm for stable cutting

Consistent productivity from PVD-coated carbide

The PVD-coated AH8015 grade provides a measured balance between wear resistance and cutting-edge stability, especially when machining heat‑resistant alloys. As an ISO-standard insert, it integrates predictably into production chains, reducing setup variability and enabling consistent cycle times. The coating enhances thermal resistance so that higher cutting speeds become feasible without premature flank wear, resulting in a predictable tool life and fewer unscheduled tool changes.

Geometry and mounting for reliable chip control

The rhombic CNMG shape paired with a doppelseitig chipbreaker geometry allows reversibility and effective chip control in both external and internal turning. The central, cylindrical hole secures repeatable clamping and orientation on standard holders, while the 0° clearance angle and included 80° approach geometry support stable engagement with the workpiece. This combination reduces vibration and improves surface finish during conventional and semi-finishing passes.

Practical benefits for workshop workflows

With a corner radius of 0.8 mm and a plate thickness of 4.76 mm, the insert delivers a reliable contact area for stable cutting and predictable edge behaviour under moderate depths of cut. The double‑sided design halves tool cost per edge compared with single‑side alternatives. Compatibility with commonly used external holders and boring bars streamlines inventory and minimises adapter or holder changes, helping to keep downtimes short and throughput high.

Choosing the right grade and application tips

The AH8015 composition is recommended as a first choice for the general machining of heat‑resistant alloys where a compromise between wear resistance and edge toughness is required. For best results, pair the insert with a holder that matches the CNMG form, tolerance class and clamping method; select feeds and speeds taking into account the workpiece material and machine rigidity to exploit the insert’s balanced performance without over‑stressing the cutting edge.

FAQ

What materials is this insert suitable for? This CNMG 090408 AH8015 insert is primarily intended for the machining of heat‑resistant alloys; the AH8015 grade balances wear resistance and edge stability for such materials.

How does the PVD coating benefit cutting performance? The PVD-coated surface on the AH8015 grade offers improved thermal protection and reduced adhesion, which helps maintain edge integrity and extend the insert’s usable life under elevated cutting temperatures.

Is the insert reversible and how does that affect cost? The double‑sided design allows the indexable insert to be rotated to a fresh edge, effectively doubling the number of usable cutting edges and lowering cost per edge compared with single‑edged inserts.

Which holder types are compatible with this insert? Compatibility is determined by insert form, free angle, tolerance class, clamping and size; the CNMG090408 form fits standard CNMG external holders and boring bars when the holder matches the ISO specifications.
